Overview
Flutter Scalable OCR is a Flutter package that wraps Google ML Kit's text recognition, enabling users to define specific regions of the camera view for text processing. This allows efficient and targeted OCR operations, reducing unnecessary computation by focusing only on relevant areas. Ideal for document scanning apps, it supports both Android and iOS platforms. The package enhances performance and accuracy by limiting analysis to selected zones within the camera feed.
Use cases
- Document scanning with focused region detection
- Real-time text extraction from partial camera views
- Mobile apps requiring efficient OCR processing
- Barcode or form field recognition in limited areas
- Reducing processing load in camera-based OCR apps
Key features
- Region-of-interest text detection
- Integration with Google ML Kit
- Support for Android and iOS
- Optimized performance through selective processing
- Simple API for defining crop areas
Suitable for
- Developers building document scanner apps
- Apps needing real-time OCR on specific screen regions
- Projects aiming to reduce OCR resource usage
- Mobile applications using camera input for text extraction
- Teams leveraging Google ML Kit with fine-grained control
Considerations
- Requires camera permissions on both platforms
- Performance depends on defined region size
- Limited to text recognition (not other ML tasks)
- Depends on Google ML Kit's availability and updates
- May need additional handling for complex layouts or low-light conditions
